PILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 411,085, datedSeptember 1*?, 1889.

Application filed November 22, 1887. Serial No. 255,895. (No model.)

.T0 all whom, it may concern.-

Be it known that I, WILLIAM HENRY BAIE- sTOW, a subject of the Queen ofGreat Britain and Ireland, residing at 29 East Castle Street,Bridgenorth, in the county of Salop, England, have invented a certainnew and useful Pile Fabric, of which the following is a specification.

This invention relates to a new article of manufacture, consistingofafabric combining all the elements of, say, for instance, a sixcarpet,(although I do not confine myself to six frames, as Inore Aor less maybe used with equal advantage, but I have simply described a six-framefabric for illustrating my invention,) in which not more than three (orhalf the number) of the warp-threads used are at any time buried in theback or ground of the fabric, instead of five threads being buried, asis the oase with six-frame Vilton or Brussels carpets.

4warp-threads of the double fabric before it is cut apart, and Fig. 2asection at right angles to Fig. 1.

In carrying out Iny invention two fabrics or cloths are simultaneouslywoven together, and are afterward divided by .any suitable cuttingdevice on the line 0c 0c, Fig. 1.

Referring to the accompanying drawings, ct represents the warp-threadsor colored yarn which form the pattern gb b2 b3 b4, the weft or shuttleshots; c, the ground-chains, and d stuffer or filling threads.

In commencing to weave the fabric let it be supposed that thewarp-threads have been equally divided by the jacquard, so that thethreads 1 2 3 (which, for example, may represent drab, red, andlight-blue threads, respectively) are raised and the threads 4 5 6(which may, respectively, represent dark-blue, gold, and bronze threads)lowered. With the warp-threads in this position, the weft-shots b (whichmay be white, for example) on the right-hand side of Fig. 1 aresimultaneously thrown by two shuttles, after which the threads 1 2 3 and4 5 G are respectively lowered and raised by the jacquard and thecomber-board. The threads 1-2 3 required to form the pattern pass directto the lay bottom, the rest of the threads, having been trapped,remaining in the center of the shed, while the threads 4 5 6 required toform the pattern rise to the top. The rest of the said threads arebrought by the coInber-board to the center in the same line as thosetrapped from the top, and then the shots b2 (which may be white) arethrown by the shuttles. The stuffer or iilling threads CZ are thenlowered in the top cloth and raised in the bottom cloth to the center ofthe shedding, and then the shots b3 are thrown. The threads 1 2 3 and 45 6 and the stuffingthreads are then returned to their former positionsby the jacquard, the comber-board, and the stuffer-thread heddles, afterwhich the shots b4 are thrown. Thus far the heddles which operate thechain c have remained unaltered; but after the shots b4 have been thrownthe said chain-heddles reverse their positions, causing thechain-threads c to cross fromover to under, and vice versa, so as tobind the warp-threads and the stuffer or filling threads with theweft-shots b b2 b3 b4 above and below, as shown in Fig. 1, after whichthe shots b and the operations hereinbefore described are repeated untilthe desired length of double fabric is completed.

The fabrics maybe divided as the Weaving progresses, or afterward, ifdesired.

It will be seen that the stuffer or filling threads d do not pass fromone fabric to the other, but lie in the ground of the fabric. It willalso be seen that of the six sets of warpthreads used never more thanthree of them are at any time buried or woven inthe back or ground ofeach fabric, and when one of the sets of threads in each fabric is beingWorked into the pile to form the pattern there are only two sets buriedor Woven in the back or ground of each fabric, while the threads whichform the pile are 'more eifectually bound in the body of the fabric bythe stuffer or filling threads d and the shots h3.
